1 Claim.

The invention relates to new and useful improvements in a friction topcan of the type wherein a nozzle is provided through which the contentsmay be dispensed, which nozzle may be closed by a friction cap.

An object ofthe invention is to provide a nozzle for a can of the abovetype which is connected to the can end close tothe side edge of the canand in such a way as to provide a relatively free pouring surface at theinside of the can in the region of the nozzle so as to avoid anytrapping of the liquid content of the can during dispensing.

A further object of the invention is to provide a can of the above typewith a friction closure cap which is adapted to engage over the upperportion of the nozzle for protecting the same durlng shipment and forreclosure purposes when the seal of the can has been broken fordispensing the contents thereof.

A still further object of the invention is to provide a can of the abovetype wherein the nozzle is formed from a single piece of drawn metal,and wherein the outer end of the nozzle is scored close to the edgethereof to facilitate a rupturing of the metal to break the seal of thecan for dispensing purposes.

In the drawing- Figure 1 is a view showing partly in side elevation andpartly in section a can embodying the improvements;

Fig. 2 is a plan view of a portion of the can;

Fig. 3 is 'an enlarged sectional view showing the can end and the nozzleassembled preparatory to the clinching of the interengaging hooks forthe seaming of the nozzle to the can end, and

Fig. 4 is a view similar to Fig. 3, but showing the nozzle fully seamedto the can end.

In the present illustrated embodiment of the invention, the can includesa body portion I to which a bottom end 2 is seamed. A top end 3 is alsosecured to the body portion I by a double seam 4. This top end has anopening formed therethrough relatively close to the side edge of thecan. The metal surrounding the opening is rst bent downwardly to providean annular hook portion 5. A nozzle 6 is drawn from a single piece ofmetal so as to provide a cylindrical wall 1 closed at the outer end byan integral portion 8 which is scored at 9. The score line is locatedclose to the vertical wall 'I and extends all the way around except fora small section which is sufficient to support the part which is to beruptured and torn away so that it will not drop into the can. When themetal is ruptured along the score line an (or 22o-44s) opening will beprovided which is of substantially the same diameter as the innerdiameter of the nozzle. vBy forming the score line close to the innerwall of the nozzle, a nozzle Amay be used which is relatively4 small indiameter and at the same-time providea f-ree pouring/opening throughwhich the contents may be dispensed. With this relatively small nozzlehaving an unobstructed pouring opening, the surface over which thecontents flows is relatively narrow, which is of great advantage indispensing the contents of the can. The nozzle at the lower end thereofhas an outwardly extending flange I0 which is bent upwardly at its outerend to provide an annular hook I I adapted to engage the hook 5 on thecan end.

After the nozzle has been assembled inthe can end as shown in Figure 3,it is then subjected to a bumping operation for locking the hookstogether as shown in Figure 4. During this bumping operation it is notedthat the hook II on the nozzle is turned to a position so that it liesin a plane parallel kwith the plane of the can end. Likewise, the hook 5on the can end is turned into a plane which is parallel with the planeof the can end. During this bumping operation, the metal of the can endis offset upwardly, and this together with the positioning of the hooks,places the lower surface of the ange of the nozzle in alinement with theinner surface of the can end. The raw edge of the metal of both the canend and the nozzle are concealed within this seam which joins the nozzleto the can end.

It will be noted from the above that a onepiece nozzle of simpleconstruction is attached to the can end by a seam which leaves little orno projecting portion at the inner side of the can, and therefore, whenthe can is turned to a position for dispensing the contents thereof,there will be little or no trapping of the contents. When the nozzle ispositioned close to the side edge of the can, this also aids in thecomplete emptying of the can through the nozzle.

A friction cap I2 is provided, which cap is drawn from a single piece ofmetal. The cap is dimensioned so as to engage over the nozzle and maketight frictional contact therewith. The lower edge of the cap I2 iscurled outwardly and upwardly as indicated at I3. The depending skirt ofthe cap is of such length as to permit the cap to lit tight against theupper end of the nozzle. The cap is placed on the nozzle and protectsthe scored end of the nozzle from blows which might rupture the metalalong the score line. Inasmuch as the cap engages the outer surface ofthe nozzle, the end of the nozzle may be closed and scored as described,and furthermore, a relatively small nozzle may be used and placed closeto the side edge of the can. It is noted that the nozzle extends onlyslightly above a plane containing the upper edge of the double seam.This is suicient to enable the contents to be poured from the nozzlewithout contacting with the double seam, and at the same time, thenozzle is well protected when the cap is applied thereto during shipmentand handling of the can. When it is desired to open a can, the nozzle isremoved and the metal ruptured along the score line. This produces, asnoted above, a pouring opening which is substantially the full size ofthe inner diameter of the nozzle. The can may be re-closed by placingthe cap on the nozzle, and through the frictional contact of the capwith the nozzle, a comparatively tight reclosure seal can be obtained.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is-

A friction top can comprising a body portion, an end seamed to said bodyportion and having an opening therethrough adjacent the side wall of thecan, the metal of the can end surrounding the opening being turned backto form an annular hook which is substantially parallel to the plane ofthe end, a nozzle formed from a single piece of metal, said nozzlehaving a cylindrical portion fitting the opening in the can end and a.closed integral outer end provided with a score line disposed adjacentthe edge of the end of the nozzle so that when the metal is rupturedalong the Vscore line a pouring opening is provided which is ofsubstantially the same diameter as the inner diameter of the nozzle,said nozzle having at the lower end of the cylindrical portion anoutwardly extending flange bent back so as to form an annular hook whichis interlocked with the annular hook on the can end, said ange and saidhook being substantially parallel to the plane of the end, saidinterlocked hooks being offset upwardly relative to the plane of the endso that the lower surface of the flange of the nozzle is in alinementwith the under surface of the end, and a friction cap adapted to engageover said nozzle for protecting the same during shipment and forreclosure purposes after the dispensing of the contents of thecontainer.
